Abstract
Systems and methods for implementing a code cache (CC) architecture are provided. For discontinuous requests, the CC forwards the request to memory while also checking the buffer for the data. If in the buffer, the CC serves the data from the buffer and discards the memory response. If not, the CC serves the data upon receipt from memory. For linear requests, the CC looks ahead on the prior request to the next address, checks the buffer, and stores the lookahead result. Upon receiving the linear request, the lookahead result is checked to determine whether the data is in the buffer. If so, the CC serves the request from the buffer. If not, the CC forwards the request to memory. In all cases, logic to determine whether the data is in the buffer does not slow down the response time from the CC.
